BUTTERFLIES OF THE VICINITY OF NEW YORK CITY 
87. Nisontades icelus. 
Not rare in open woods, and especially along wood paths. It flies 
during May and June. It is single-brooded. The caterpillar feeds 
on aspen, willow and witch-hazel. 
88. Nisoniades persius, 
Allied to NV. Jucilius, but is larger, with the markings less distinct. 
It is quite common locally, in woods and along shady roadsides. It 
is single-brooded and flies during May and June. The caterpillar 
feeds on willow and poplar. 
89. Nisoniades martialis. 
Quite scarce in this vicinity, and found in localities similar to 
those in which are found other species of Nisoniades, in May and 
June, and again in July and August. The food-plant is said to be 
wild indigo (Indigofera carolina).
